I'm not sure what you mean about a 12 volt to usb adapter. Are you talking about the thing that sticks into a cigarette lighter and has a female usb on it? If not could you send a picture of what you mean?
And wouldn't I need a power inverter to use the adapter? I'm assuming that they can't just be easily hooked on a battery, or can they?
And I bought the 10 amp kit but can easily cancel it on amazon as it probably won't ship until Monday
He's basically talking about a universal car charger. Plugging something into a cigarette lighter is electrically the same as connecting to a battery, the exception being is that more current (amperage) is available when connecting directly to a battery. Not a factor in powering a USB port.
Using a power inverter to power a USB port would be incredibly inefficient, if that what's you're referring to when you mention the power inverter to use the adapter. You would be converting 12V to 120V and back to about 5V.
